Pathological complete response (pCR) rates range from 0 to 18 % while breast-conserving surgery (BCS) is achievable in up to 60 % of tumors. No pathological feature definitely predicts pCR; lobular and molecular luminal A tumors are less likely to achieve pCR although experiencing better outcomes. Luminal B subtype, high proliferation, lack of progesterone receptor, high tumor-infiltrating lymphocytes are positively associated with increased pCR rates but worse outcomes and the prognostic role of pCR is inconsistent across studies. Molecular intrinsic subtyping and genomic signatures appear as more accurate predictors of benefit from NACT, but larger studies are needed. Anthracycline and taxane-based chemotherapy remains the standard NACT; however, CDK 4/6 inhibitors and immune checkpoint inhibitors are under evaluation. In conclusion, NACT may be proposed for luminal tumors requiring downsizing for BCS after multidisciplinary evaluation, provided that other contraindications to BCS are excluded.Glioblastoma, the most common primary brain malignancy, is an exceptionally fatal cancer. Lack of suitable biomarkers and efficient treatment largely contribute to the therapy failure. Cytoskeletal proteins are crucial proteins in glioblastoma pathogenesis and can potentially serve as biomarkers and therapeutic targets. Among them, GFAP, has gained most attention as potential diagnostic biomarker, while vimentin and microtubules are considered as prospective therapeutic targets. Microtubules represent one of the best anti-cancer targets due to their critical role in cell proliferation. Despite testing in clinical trials, the efficiency of taxanes, epothilones, vinca-domain binding drugs, colchicine-domain binding drugs and γ-tubulin binding drugs remains to be confirmed. Moreover, tumor treating field that disrupts microtubules draw attention because of its high efficiency and is called "the fourth cancer treatment modality". Thereby, because of the involvement of cytoskeleton in key physiological and pathological processes, its therapeutic potential in glioblastoma is currently extensively investigated.The results of clinical trials performed from the 1930s until the end of the 20th century in which total-body ultra-low level ionizing radiation (TB-LLR) was used demonstrate that this form of treatment can be equal or superior to other systemic anti-neoplastic modalities in terms of the rates of remissions, toxicity, and side effects. In this review, we provide the rationale for TB-LLR and analyze the results of reliable clinical trials in patients with predominantly lymphoproliferative disorders but also advanced solid cancers. The doses used in these trials did not exceed 0.1-0.2 Gy per fraction and cumulative totals ranged from 1 to 4 Gy. Based on the reviewed results we conclude that it is appropriate to revive interest in and resume clinical investigations of TB-LLR in order to refine and improve the effectiveness of such treatment, whether employed alone or in combination with other anticancer strategies.While medical imaging plays a key role in diagnostic and treatment guidance, evidence shows that the number of investigations using ionizing radiation has greatly increased over the last decades, which could be a concern among paediatric patients. Repeated imaging, as required for certain congenital conditions is of particular interest in regard to cumulative dose and the associated risk of cancer. In this context, the aim of the current work is to systematically collate and evaluate the findings reported in the literature over the last 10 years, based on the imaged anatomical area, in order to identify trends, consensus and/or discrepancies in reported risks.
Two databases (MEDLINE, and Scopus) were systematically searched for literature published between 2010 until July 2020. Randomized clinical trials (RCTs), controlled clinical trials (CCTs), prospective and retrospective cohort studies, and case series (with ?10 cases) were sought. Forty-five studies met eligibility criteria for inclusion in the revit conditions in order to evaluate the most optimal choice for each situation.Glycoconjugates are involved in several pathological processes. Glycomimetics that can favorably emulate complex carbohydrate structures, while competing with natural ligands as inhibitors, are gaining considerable attention owing to their improved hydrolytic stability, binding affinity, and pharmacokinetic (PK) properties. Of particular interest are the families of α-d-mannopyranoside analogs, which can be used as inhibitors against adherent invasive Escherichia coli infections. Bacterial resistance to modern antibiotics triggers the search for new alternative antibacterial strategies that are less susceptible to acquiring resistance. In this review, we highlight recent progress in the chemical syntheses of this family of compounds, one of which having reached clinical trials against Crohn's disease (CD).Adhesion after a tendon injury is one of the major problems following upper extremity surgery. In the present study, we evaluated a new material that is clinically usable as an adhesion barrier. Twenty-four male Wistar albino rats were used in the study. These rats (48 legs) were divided into three groups sham, control, and experimental. No surgical intervention was performed in the sham group. After making a full-thickness cut through the right Achilles tendon, the tendon was repaired using the modified Kessler technique in the control group, while bovine collagen matrix was wrapped around the surgically repaired tendon using the modified Kessler technique in the experimental group. Two months after surgery, the operated and non-operated tendons were resected and analyzed through biomechanical, macroscopic, and histopathological examinations. The results of the biomechanical testing did not differ significantly between the control and experimental groups. Macroscopic examination of the adhesions revealed less adhesions in the experimental group but this difference was not statistically significant.
